When you connect the 1x40G cable to the N3000. what is the output of fpgainfo phy? UP or DOWN?

I just found that result changes all the time,

e.g.1 e.g.2 e.g.3

Port0 10G           : Up   : Up    : Down

Port1 10G           : Down   : Up : Down

Port2 10G           : Down   : Up     : Down

Port3 10G           : Down   : Up    : Down

Port4 10G           : Down : Down  : Down

Port5 10G           : Up          : Up       : Up

Port6 10G           : Up          : Up       : Up

Port7 10G           : Down     :Down   :Down

Hi @fzhan51​ , When you say 1x40G, it is only 1 port at 40G, right?

Or, Do you mean 4x10G instead? Because the the card can only support 10G per port.

1 port at 40G , 4X10G fiber test sucess. now I am confused.

1 port at 40G --> it makes sense it will FAIL because the card supports 10G per port

4 port at 10G each --> it makes sense it will PASS because the card supports 10G per port

 

Im not sure there is such cable as 1 port at 10G --> then this will further confirm my explanation.

 

Btw, 1x40G is NOT EQUAL to 4x10G !!
